经过一天的故障排除后，我设法将问题浓缩为这一小段代码。有人可以向我解释为什么这不起作用吗？当显示消息框时，我希望 [markets] 为 0 2 4 6，[city] [county] 和 [streets] 为 0 1 2 3。

        private void pieceoftestcode()
        {
            string[] county = new string[4];
            string[] city = new string[4];
            string[] markets = new string[4];
            string[] streets = new string[4];
            string[] items = new string[4] { "apple", "banana", "pineapple", "juice" };
            string[] value = new string[4];
            foreach (string item in items)
            {
                for (int i = 0; i <= 3; i++)
                {
                    if (item == "apple")
                        value[i] = (2 * i).ToString(); …
